Suara.com – Some people may need to tune in to certain songs or musical instruments while studying. This habit turns out to be useful for optimizing the work of the brain in receiving information, you know. Especially activating alpha waves in the brain.
However, you need to pay attention to the type of music you listen to. To help the brain think, it is recommended to listen to music or sounds of calm natural nuances.
“That’s called alpha waves. Alpha waves are waves in the brain that make the body more relaxed,” said neurologist Dr. Zicky Yombana, Sp.S., met at Neuro Care by Klinik Pintar, Jakarta, some time ago.

He explained that alpha waves in the brain are easily stimulated by sounds like white noise or like a waterfall. Not only can it be used by adults, according to doctor Zicky, this type of sound can also help babies sleep.

When the brain is in alpha wave condition, the information received can also be better.
“So there is the term alpha learning. Conditions with alpha waves, we learn it goes in. So if you want to learn, don’t listen to rock songs, listen to the sounds of nature,” he suggested.
Alpha waves in the brain can also appear naturally when someone is daydreaming or while meditating. The waves have a strength of about 8–12 Hz. A person can also reach these waves while undergoing certain activities, for example doing aerobic exercise.
Quoted from Alodokter, there are still four brain waves that can occur in humans, depending on activity, thoughts, emotional state, and sleep patterns. Brain waves are measured by frequency in hertz (Hz).
1. Delta waves

Delta waves are the slowest and occur while sleeping. The strength of these waves is very low, which is around 1–4 Hz. Delta waves also appear when meditating. These waves are thought to play a role in the healing process when sick and improve sleep quality. Delta waves are also believed to have an important role in the functioning of the digestive system and heart.
Injury to the brain can cause delta wave activity to increase so that a person is often sleepy. Having too much delta wave activity can also lead to attention deficit hyperactivity disorder (ADHD).
2. Theta waves
Theta waves also occur during sleep and meditation. This brain wave range has a greater power, which is 4–8 Hz. Theta waves have a close relationship with memory or memory as well as the level of consciousness and the body’s natural sleep cycle. This brain wave pattern is also associated with the phenomenon of dreams and lucid dreams.
However, until now, the effect of theta type brain waves on brain work processes in general is not known with certainty.
3. Beta waves
This wave activity is quite high, which is around 12–35 Hz. Beta waves are associated with high levels of awareness, alertness, focus and arousal. Beta waves also usually appear when someone is thinking or making a decision.
4. Gamma waves
Gamma waves are brain waves with the highest strength, which ranges from 25–100 Hz. However, the average gamma wave in a person’s brain has a range between 35-40 Hz. Gamma waves appear when processing and studying information simultaneously and are associated with a higher level of consciousness.
